The underside of leaves is where the 'stomata' are to be found in most (not all) plants and it is through these stomata that the gas exchange occurs. The upper surfaces of leaves are usually tough and shiny to protect the leaf and shed water. If the stomata were on the upper surface and the leaf was wet, the water would block them and impede gas exchange.
The stomata are located on the lower surface of a leaf.
stomata is present on a leaf's lower surface. but in plants that float on water, stomata is present on a leaf's upper surface, and the lower surface is protected by a coating of wax.
There are about 92 stomatas on upper surface and 39 stomatas on the lower surface. In a dorsiventral leaf number of stomata is more on the lower surface hence the above answer may please be verified
Most water loss occurs from the lower surface of the leaf because it has more stomata, which are tiny pores that allow water vapor to escape during transpiration. The lower surface is also less exposed to direct sunlight, reducing the risk of excessive water loss through evaporation.
because clorophyll is there
When light strikes a leaf, it can be absorbed, transmitted through the leaf, or reflected off the surface. Absorbed light is used in photosynthesis to produce energy for the plant. Transmitted light passes through the leaf to reach other parts of the plant, while reflected light bounces off the leaf's surface and can be used for other purposes.
Water cannot be absorbed through the surface of a leaf.
Water cannot be absorbed through the surface of a leaf.
Water cannot be absorbed through the surface of a leaf
The upper surface of a leaf is transparent because it lacks chloroplasts which carry out photosynthesis. This allows light to pass through the upper surface and reach the chloroplast-rich cells in the lower side of the leaf where photosynthesis occurs.
So more light falls on. More energy is absorbed
The upper side of a leaf is referred to as the dorsal side. It is also known as the adaxial surface and is typically darker in color compared to the lower side, which is called the ventral side or abaxial surface.
